PSYA01H3 Lecture Notes - Lecture 10: Frontal Lobe, Prefrontal Cortex, Reduced Affect Display
Document Summary
We got input coming in to all of the lobes. Motor strip allows you to output: move, behave, etc. The pre-frontal cortex tries to figure out before you act what you should do (strategizing, thinking, problem solving) Damage from sensory strip you (cid:449)o(cid:374)"t feel a(cid:374)ythi(cid:374)g fro(cid:373) that part of the (cid:271)ody (cid:894)(cid:374)u(cid:373)(cid:271)(cid:895) Frontal labotomies: surgical procedure of the frontal lobe to sever the connecting fibres from other areas, effects: Slowing of thoughts and loss of spontaneity (same old thing) Perseveration error keep doing it the wrong way that once was right but now changed and not correct.
